surfboard Fins FCS H4

FCSll H4 Quad Rear surf fins look and behave differently compared to other fins. Swiss engineering precision combined with a highly evolved model provides an unprecedented level of control and predictability at high speed.

UNIQUE TEMPLATE

While the science behind the template, the materials and the foils are very complex. Each component of this fin has been designed to create a simple synergy between the fin and the surfboard, the rider and the wave.

REAR FINS SYNERGY: The H4 quad combines the power + control of the H4 thruster, with the added speed and handling of a quad.

REAR QUAD PROFILE: A similar hybrid contour on the front and rear fins helps minimize turbulence + provides a smooth, predictable feel.

IMPROVED SHEETS: Revolutionary new blade designed to grip longer turns and promote seamless rail-to-rail transitions.

Ideal conditions:

A wide range of conditions, particularly good in critical aerial waves.

Types of tables:

Designed to fit the FCS II fin system.
Recommended for performance short boards with moderate to low rocker.

Fin family

Throttle: find control. Speed, flow and response with additional control.

Building:

- PRECISION AND SWISS DESIGN: Creates a perfect synergy between the geometry of the fin and the HI-FI materials, giving a smooth and predictable feel.

- HIGH DENSITY UNIDIRECTIONAL CARBON FIBER: Lightweight and super strong with custom orientation to transfer more energy at speed than any other fin.

- DYNAMIC TRAILING EDGE: The internal compound transforms under extreme load, allowing the fins to be pushed harder without sliding out.
INNOVATIVE PRODUCTION: Highly specialized robotic automation combined with camera-assisted quality control ensures absolute precision.
